The Huckleberry mine located in British Columbia produces roughly 40 million lb/y of copper. A comprehensive energy and cost study compared an existing SAG mill-based circuit at the Huckleberry mine with two proposed circuits involving comminution technologies that are associated with energy efficiency high-pressure grinding rolls (HPGR) and high-speed stirred mills.
Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However as the grind size coarsens the difference in specific energy required to achieve the grind lessens.
power models found in the literature followed by a general description of DEM and CFD stirred mill models as well as the insights that can be drawn from them. Finally a generic stirred mill power model will be presented and applied to different stirred mill types in order to develop some insights into the differences between different mill types.

The large scale of the IsaMill™ makes that efficiency available to mainstream grinding. The high energy efficiency of stirred mills compared to ball mills is well understood. The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a common inclusion in the latter part of the previous century.
The IsaMill (high capacity horizontal stirred mill) is referred to as an enabling technology. Through significantly lowering the cost of fine grinding many locations that had high grade but fine-grained ore became economical. Stirred mill technology energy efficiency is extremely dependent upon several variables including grinding media selection.
Stirred media milling is an industrially accepted efficient grinding method for fine and coarse particles. The stirred mills can be operated both in vertical and horizontal configurations and the
Comminution is an energy intensive process. A small change in efficiency can lead to substantial benefits in an overall economy of the process plant. This study focused on the comparison of vertical stirred mill agitator designs. A double helical screw agitator was designed for this purpose.

Ceramic grinding media is resistant to abrasion and is an ideal media for stirred milling especially when compared with steel. A compact simple installation and process The typical HIGmill flow sheet for regrind circuits is simple and straightforward.
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill usually a high-carbon steel can vary in both the length and the diameter. However the smaller the rods the larger is the total surface area and hence the greater the grinding efficiency. Autogenous mill
largest stirred mill the M10 000 IsaMill. 1 INTRODUCTION The high energy efficiency of stirred mills compared to ball mills is well understood within the industry. The use of tower mills as an energy efficient alternative to secondary and regrind ball milling became a standard flow sheet inclusion in
The IsaMill is a stirred-medium grinding mill in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
A more recent trend in stirred mill classification is based on the tip speed (tangential velocity) of the mill impellor. Low speed mills are those with a tip speed below 3 m/s while high speed mills operate at speeds greater than 15 m/s. The effective size reduction limit for these two speeds are
